IN ADDITION, MAKE SURE THAT EVERY INDIVIDUAL WHO OPERATES OR WORKS WITH THIS EQUIPMENT, WHETHER FAMILY MEMBER OR EMPLOYEE, IS FAMILIAR WITH THESE SAFETY PRECAUTIONS. Gehl Company always takes the operator and his safety into consideration when designing farm machinery and guards exposed moving parts for his protection; however, some areas cannot be guarded or shielded in order to assure proper operation. I n addition, the operator's manual and decals on the machine itself warn you of further danger and should be read and 0 bserved closely. The safety alert symbol above means ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! It stresses an attitude of"heads UP" for safety and can be found throughout this operator's manual and on the unit itself. Remember: The careful operator is the best operator. Most accidents are caused by human error. Certain precautions must be observed to prevent the possibility of injury or damage. Please read the rules listed below for safe operation BEFORE you operate this equipment. Wheel Rake operation is a function of the travel of the tractor; to stop the Rake stop the tractor! The operator MUST be seated on the tractor at all times to operate this unit! Clear the area ahead of all spectator and obstacles BEFORE proceeding to operate this unit! Make sure that there is ample clearance below electrical wires BEFORE transporting Rake! DO NOT allow minors to operate or be near the Rake unless properly supervised! DO NOT allow personnel other than a qualified tractor operator near the Rake! DO NOT wear loose or baggy clothing when operating the Rake! DO NOT exceed tractors Top Link adjustment limit! DO N.OT attempt to detach Rake from tractor 3 point hitch with Rake Flotation Springs locked in "Transport" positions. Doing so may cause serious injury from pressure that is NOT relieved from Top Link connection to tractor. Correct procedure is detailed under Assembled V-Rake Tractor Connection topic in this manual! 8

Positions of the Finger Wheels on either model can be changed to enable the largest working width for large raking capacity. As conditions require,. the Wheel angles can be changed to accommodate wide or narrow, or light or heavy, 'cut crops. Fig. 1 The Finger Wheel pressure on the ground is most important to achieving clean raking. If too much pressure is applied against the ground, unnecessary dirt and trash will be brought in the windrow. SET-UP & ASSEMBLY Before proceeding to set-up and assemble either Rake, uncrate the unit and spread the components out in an organi7.ed manner. Remove paint and plastic covers Crom the turning parts, such as the Finger Wheel Carriers, Turning Bars and Hinge Bars. Proceed as follows: Main Frame and Mounting Brackets To facilitate assembly, mount the components directly onto the 3-point hitch of a tractor. An optional Category I Lift Tong can be obtained and substituted for mounting either model Rake on a tractor with Category I provisions. I. Fasten the Main Frame to the tractor hitch (Fig. I). Category II Pins are standard equipment for the Top Link and Lower Lift Arms of the 3-point Fig Raise the tractor 3-point hitch so the bottom of the Main Frame is approximately 24" (61 0 mm) above the floor. 3. Adjust the Top Link so the Main Frame is perpendicular with the ground. 4. Install the left Top Mounting Bracket with the hole in the Pivot Pin up and toward the rear (Fig. 3) and secure it with (2 each) M 12 x 30 and M 12 x 90 CS. Tighten the Bolt only tight enough to keep the Bracket from moving. 5. Install the right Top Bracket in the same manner. 6. Install the Bottom left Mounting Bracket with the Width Adjustment piece and Hinge Arm facing the rear of the Rake (Fig. 3). 9

10 3. Press the Plastic Cap down firmly over the Top Mounting Bracket Pin and Roll Pin. 4. Insert the lower end ofthe Tension Spring assembly through the Bracket on the Main Hinge Bar (Fig. 4). Insert from the opposite side where the hooked end of the Tension Spring is positioned. Fig.3 NOT E: The Pivot Pin on the Lower Bracket MUST be directly below and in-line wi th the Pin on the Upper Mounting Bracket. (Fig. 4) Pass the lower Bolts from th e rear toward the front, through the two Plates and secure th em with the appropriate hardware. Refer to the parts illustration for fastener details. 5. Attach the Tension Spring Adjusting Plate, over the Spring Hook. Then, slip it over the bottom end of the Telescoping Bar and up against the Bracket. Secure the assembly with the Hairpin Cotterpin. To insert more pressure on the Finger Wheels, place the hook end of the Spring in the top holes (Fig. 6). 1"0 lessen the Finger Wheels pressure, place the hook end of the Spring in the lower holes (Fig. 5). 7. Install the right Bottom Bracket and the Hinge Arm in the same way as the left Bottom Bracket. Again, align the Pivot Pin directly below the Pin on the Upper Mounting Bracket. Tension Spring 1. Slip the large end of the Coil Spring over the flat end of-the Telescoping Bar (Fig. 4). It will be necessa ry to exert a good deal of force to make the Bar pa ss through the smaller portion of the Spring. Push the Spring down to make su re that it is seated firm ly against the Stop of the Telescoping Ba r. Fig Slip the hole in the top end of the Telescoping Bar over the Upper Pin on the Top Mounting Bracket (Fig. 4). Fasten the Pin by driving a Roll Pin through the hole in the end of the Pin. Fig. 6 Fig.4 6. Raise the Main Hinge Bar so that the Transport Pin can be passed through the Inside Telescoping Rod and secure it with the Hairpin Cotterpin. The Transport Pin, when removed from the Tension Spring for operating the Rake, should be stored in the Transport Hole on the Rake Width Adjusting Bracket. (Fig. 15) 10

Install the (610894) Plastic Bearings into the Main Turning Bar. 2. Attach the Main Turning Bar to the Main Hinge Bar and secure it with the Locking Pin and Hairpin Cotterpin (Fig. 7). Make sure the curved end of the Main Turning Bar is pointing to the front. 5. Repeat steps 1 through 4 for the other half of the Rake. The Front Finger Wheel Carriers have their Spindles nearest the bend at 15" (381 mm) (Fig. 9). The rear Finger Wheel Carriers have their Spindles further away from the bend at 21" (533 mm) (Fig. 9). DO NOT attempt to drill holes and mix-up the assemblies. Locking Pin & Hairpin Cotterpin." ~..-,.;-r'" """"'-"''f''::: Fig.7 3. Apply a light coat of motor oil on the Spindles of the Finger Wheel Carriers. 4. Attach the Finger Wheel Carriers to the Main Turning Bar and secure them with the Locking Pins and Hairpin Cotterpins (Fig. 8). W R308 Fig.8 Assembly procedures are the same as for the WR310 except that the Main Turning Bars are positioned and a ttached with their curved end facing the rear of the Ra ke (Fig. 10). 15" (381 mm) 21" (533.5 mm) Fig. 9: WR310 11

12 15" (381 mm) 15" (381 mm) Fig. 10 Finger Wheels It is most important that the appropriate Right and Left Finger Wheels are installed on their proper sides of the Rake. The Finger Wheels are tagged before shipment with right and left designations. Ifthe tags are removed in shipment, determine whether it is a right or left Finger Wheel by the following deduction. Stand the Finger Wheel up with its smooth side facing you. The smooth side is the side with the Bolt Heads. View the Bolt Heads on the Finger Wheel and follow the Tines up to their ends to see which way they turn. If the Tines turn to the right, the Wheel is a right Finger Wheel or, if they turn left, it is a left Finger Wheel. shown in Fig. II. The Closing Ring MUST also be correctly positioned and assembled so that the small alignment dimple fits into a mating recess on the Axle Shaft to prevent the Closing Ring from turning. Attach and secure the Ring with the 10 mm Bolt provided. For a WR308 Rake after Serial #2552 or for a WR31 0 Rake after Serial #2402, the Closing Ring MUST be correct ly positioned and assem bled so that the small hole for the Roll Pin is lined-up with the mating hole in the Axle Shaft as shown in Fig. 12. The Roll Pin MUST then be installed to prevent the Ring from turning. Attach and secure the ring with the IO mm Bolt provided. Disassemble Finger Wheel Hubs (Figs. II or 12) from the Rear Finger Wheel Support Axle and mount them onto the Finger Wheels with the (6) Bolts provided. The Reinforcing Flanges of the Finger Wheel Hubs MUST be properly oriented to be on the side opposite the force of the crop as shown in either Fig. 11 or 12. This is necessary to insure proper support and to help prevent the Bolt Heads from fatiguing the Wheel Reinforcing Flanges. With the Wheel correctly oriented, push the Finger Wheel and Bearings onto the Finger Wheel Support. For a WR308 Rake before Serial #2663 or for a WR310 Rake before Serial #2403, BE SURE to install a Filling Ring on each side of the assembly as Fig

13 6. With the 3-point lower links attached, refer to steps 2 and 3 above for the rest of the attachment procedure. Fig. 12 V RAKE TO TRACTOR CONNECTION NaTE: The same attachment procedures apply to either the WR308 or the WR31 0 models. However, depending on the serial #, different" linkage arrangements are provided for tractor hook-up. WR308 (Before SN2661) or WR310 (Before SN2401) 1. Correctly line-up and back the tractor up to the Rake Frame so that the tractor 3-point hitch lower links line-up with the Attachment Pins on the Rake. Install the 3-point hitch lower links over the Pins and lock them with the tractor linchpins. 2. With the 3-point hitch lower links attached, raise the Rake Frame so that the Jackstands, on the Rake, can be raised and locked into their storage positions. 3. With the Jackstands locked in their storage positions, lower the tractor lower links to tip the Rake forward so that the adjustable tractor top link can be attached to the desired hole in the Attachment Bracket on the Rake Frame. Proceed to step 7. A CAUTION: Do NOT exceed the extension limit on the tractor's adjustable top link. If NO stop is provided, BE SURE to allow at least 1" (25 mm) of tube engagement between the two halves of the adjustable top link. WR308 (After SN2662) or WR31 0 (After SN2402) Removable and lock-on Category I or Catagory II Lower Link Bars (Lift Tongs) are available on WR308 Rakes (after SN2662) or WR310 Rakes (after SN2402) to facilitate Rake connection to the tractor (Fig. 13). 4. Remove the Lower Link Bar (Lift Tong) from the Rake Frame and attach it between the tractor 3 point hitch lower links. 5. Back the tractor up to the Rake Frame and use the tractor hydraulic lift to raise the Linkage Bar up and into position in the Clevis Brackets on the Rake Frame. Lock the Linkage Bar into the Clevis Brackets with the Pin provided. Fig. 13 All WR308 & WR310 Rakes 7. After the tractor 3-point hookup is made, raise the Rake and remove the Transport Pin from the "Parking Hole" in each Flotation Spring Tube (Fig. 14). Install the Transport Pin in the "Storage Hole" in the Right and Left Hinge Arm Quadrants. The Rake is now ready for field operation, after the necessary adjustments are made per the Field Adjustments topic. Refer to the Road Transport Position topic for procedures to place the Rake into transport. PARKING & UNHOOKING RAKE The following steps should be followed to detach the Rake from the tractor. After selecting a level parking spot, proceed as follows: These steps are developed in consideration of taking the Rake out of the "Road Transport" position. To detach the Rake from the field operating position skip to step 4. I. With the Rake in the transport position, leave the tractor seat and swing-out the Right and Left Hinge Arms one hole position away from the "Transport Hole" in the Quadrant so that the Finger Wheel Frames can be conveniently and more easily swung-out of their transport positions. 2. Remove the Pins and rotate the Right and Left Finger Wheel Frames to their operating (or parking) positions. 3. On WR310 Rake models only, rotate the two back Finger Wheel assemblies to their operating (parking) positions. 4. Get back on the tractor and lower the 3-point hitch so that the Finger Wheels contact the ground. Using the tractor adjustable top link, lower the Rake so that all of the Finger Wheels are in solid 13

14 Existing (or Newly Drilled) Parking Hole Existing Transport 11/16" (17.5 mm) Diameter Pin Hole Outside Tube Telescoping Bar (1 of 2) Spring Compressed Fig. 14 contact with the ground and so that the Transport Pins can be removed from the "Transport (top) Hole" in both Flotation Spring assemblies. If your earlier model WR308 or WR310 Rake is NOT equipped with two holes in each Flotation Spring assembly (Telescoping Bar), the additional "Parking Hole" should be added per the details shown in Fig U sing the tractor 3-point hitch and with the Transport Pins removed, raise the Rake enough so that the Transport Pins can be installed and locked into the "Parking Hole" in each Flotation Spring. 6. With the Transport Pins in the "Parking Holes", completely lower the lackstands and lock them in the supporting position. Then, lower the Rake so that the assembly is completely supported by the lackstands and the Finger Wheels. ' 7. As necessary, readjust the tractor top link so that it is free to be detached from the Rake. A CAUTION: Under NO circumstances, at tempt to detach the Rake from the tractor with the Transport Pins in the "Transport Holes" in the Flotation Springs NOR attempt to detach the Rake while it is folded into its transport width. 8. As appropriate, either detach the Lift Tong or otherwise uncouple the 3-point hitch lower links to separate the Rake from the tractor. BE SURE to store the Lift Tong with the Rake. ROAD TRANSPORT POSITION After the Rake is properly attached to the tractor, it can be placed into the "Road Transport" position in the following manner: A DANGER: Whenever the Rake is raised for or being transported, maintain a safe distance away from all overhead high voltage lines. Transporting the Rake requires reducing the overall width as well as providing clearance to prevent the Finger Wheels from striking the ground. 1. Lower the tractor 3-point hitch completely and install the Transport Pins into the "Transport Hole" in each Flotation Spring assembly. As necessary, readjust the top link to align the holes in the Flotation Spring Rods and Tubes. 2. With the Transport Pins installed, adjust the top link to shorten it completely and provide maximum ground clearance, when the Rake is raised. 14

15 3. Raise the Rake with the tractor 3-point hitch. Then, remove the Locking Pins, between the Main Turning Bar and the Rear Finger Wheel Carrier on both sides. Remove the Locking Pin, between the Main Hinge Bar (4 of Fig. IS) and the Main Truning Bar (3 of Fig. IS) and swing the Rake assembly up into the Transport position (Fig. 16 or 17). SPREADING Both model V Rakes can be used to spread existing windrows to help speed-up the drying process. To set the Rake up for spreading, proceed as follows: Where possible, the Finger Wheels should always be transported vertically. If this is NOT possible, because of the raising limitations of the tractor 3-point hitch, the lower pair of Finger Wheels, on both sides, can be unlocked and swung into the horizontal position, to obtain additional clearance. Fig. 17: Transport Position for WR310 Fig. 15 A WARNING: ALWAYS observe appropriate regulations for highway transporting of this or any farm equipment. BE SURE to install each Transport Pin into both Flotation spring assemblies BEFORE transporting the Rake (Fig. 14). Make sure also that all other Pins are locked in position. I. Raise the 3-point hitch to its maximum height, remove the Locking Pins between the Main Hinge Bar and Main Turning Bar and rotate the Rake unit upside down from working position (Fig. 18). a /' [\ Fig. 18 Fig. 16: Transport Position for WR308 To restore the Rake to the operating position, reverse the above procedure. BE SURE that the Main Turning Bars are rotated horizontally with the curved portions toward the rear on WR308 Rakes or the curved portions are rotated toward the front of WR310 Rakes. 2. Close the Rear Finger Wheels to approximately 18 to 24" (457 to 609 mm) apart, using both Width Adjustment Locking Pins. 3. Set the 3-point hitch Lower Hitch Pins to a height of 22" (559 mm) above the ground (Fig. I!}). 15

16 For spreading, it may be necessary to set each half of the Rake in the No. 4 or 5 hole Width position (Fig. 20) and then, to slide both Rake halves inwajd on the Main Frame until the Rear Finger Wheels are about 18 to 24" (457 to 609 mm) apart. The Finger Wheels are now appropriately situated so that each swath is split and turned without hay being passed from one Wheel to the next. Various Width Adjustment positions on the Main Frame and Wheel angles can be used with varying results depending on the type and density of the crop or hay. and minimum. Depending on the field conditions and the crop density, the good performances of the Rakes will be less likely evident when the limits are closely approached or exceeded. When the Main Frame is properly attached to the tractor 3-point hitch, it should be vertical to the ground with the Lower Hitch Pins 19" (483 mm) above the ground (See Fig. 21). Readjust the top link, as required, to position the Main Frame vertically. Using the optional Limiting Chains or the tractor position control, fix the 19" (4X3 mm) downward limit. Width Positioning Bracket The Wid th Positioning Bracket (Fig. 20) is hi nged atone end and 5 holes are provided on the other end for position selection. Hole I, which is closest to the Frame, is used for transport. The remaining (4) holes are used with desired Width settings, with hole (2) for the widest setting and hole (5) for the narrowest setting. Remember that, if the Width is adjusted, the discharge opening between the rear Finger Wheels is also changed. Position 4 or 5 MUST be used in heavy hay conditions to allow material to get out of the Rake. FIELD ADJUSTMENTS, 22" (559 mm) For Spreading Fig. 19 Both model V Rakes have the same field adjustments. Both Rakes will perform well within certain limitations based on density of the crop and the desired windrow width coming out of the Rake. The key factors to consider for proper Rake set-up are: I. The width of the swaths or windrows to be raked 2. The size of the discharged windrow 3. The density of the crop (tons per acre) In general, the WR308 will work well up to 18 ft with a 5 ft discharge windrow. the smallest setting for the Rake is IS ft with a 4-ft discharge windrow. The WR31 0 will work well up to 22 ft with a 5-ft discharge windrow. The smallest WR310 setting is 18 ft with a 4-ft discharge windrow. It should however, be well understood that the a bove limits are NOT presented as achievable maximums Telescoping Rod and Spring The Telescoping Rod and Spring assembly is mounted to the Top Bar of the Main Frame using a Mounting Bracket. The Mounting Bracket MUST be appropriately located directly over the Pivot Pin of the Lower Bracket, the Width Positioning Bracket. When the Lower Bracket is moved, the Top Bracket also moves. The Telescoping Rod Spring allows the Finger Wheels to float across the ground. Both the right and left assemblies MUST be locked so the Rods will NOT extend for transport (Fig. 14). For the operating position, these assemblies MUST be unlocked and the Transport Pins should be stored in the "transport" holes (1 of Fig. 20) of the Width Positioning Brackets. During set-up and for transporting the Rake, the Transport Pin is used to secure the Inner Rod to the Outer Tube. Lower the 3-point hitch until the Locking Pins, which are located 6" (152 mm) down from the Outer Tube when measured from the Top Mounting Bracket, can be removed. BE SURE to install the Transport Pin into the Transport Hole in the Width Positioning Brackets while the Rake is being operated. When the Rake is transported, the Locking Pins MUST be locked into the Telescoping Rod and Spring assemblies in order to remove all weight from both Springs. 16

17 Fig. 20 Tension Spring Adjuster Plate The Tenslon Sprlng Adjuster Plate is located at the end or the Telescoping Rod and Spring assembly (I of Fig. 21) and fastens the Spring to the Hinge Bar. The Plate controls the amount of pressure the Spring will allow the Finger Wheels to have on the ground. To increase the Tine pressure on the ground, lengthen the Adjuster Plate (Fig. 5). The Tine pressure may be increased to combat too much flotation, skipping hay, rough ground conditions, holes or uneven ground. The Tine pressure on the ground can be decreased by shortening the Adjuster Plate (Fig. 6). The Tine pressure may be decreased to combat undesired raking-up of stones and debris, excessive Tine wear or noisy operation. For most operations, place the hook end of the Spring in hole X. (Fig. 21) NEVER attempt to change the ground pressure by moving the Hitch Pin level, leave it at 19" (483 mm). Rake Width After the desired Tine pressure is properly set, the Rake Width and width of the windrow can be adjusted. The center of the discharge windrow should be in the center of the Rake Main Frame and the tractor. To reset the width, first start with the Width Positioning Brackets in the third hole positions (Fig. 22). This will provide the center point to work from, in most conditions. Fig

18 With the third hole position selected on both halves of the Rake, measure the distance between the last Finger Wheels to determine the size of the windrow. Measurements should be taken between the Outer Rim of the Finger Wheels at their close~t point to each other (Fig. 23). If a 5-ft windrow is desired, the measurement should be 5-ft. To adjust this distance, slide the Hinge Bar Mounting Brackets in or out equally to obtain the required measurement. Some very heavy crop condition may limit the usefulness of the V Rakes. The heavier the crop, the less the angle for moving the crop from Finger Wheel to Finger Wheel. To help prevent bunching, it may also be necessary to reduce your speed of travel. By driving slower the material is given more time to clear the Frame where bunching normally occurs. It should also be understood that too much material may be more than the baler pickup can handle. Fig. 22 The Telescoping Rod and Spring assembly Mounting Bracket MUST also be slid along. Position of the Top Bracket of the Telescoping Rod and Spring assembly should also be set directly over the Hinge Point of the Hinge Bar Mount (Fig. 24). Fig. 23 After the windrow width is set, check the raking width in the crop. Measure from Tine to the ground contact point on the first Finger Wheel across to the opposite first Tine point of ground contact (Fig. 23). After a satisfiable setting is obtained, test the operation by raking a short distance and then, stop and evaluate the area. Measure the windrowed width (Fig. 23) and readjust it if necessa ry. If it becomes necessary to rake more width to pick up the entire swath, slide the Hinge Bar Mounting Brackets out until the distance desired will be picked-up. In certain field and crop conditions, to obtain the required widths, it may be necessary to move the Lower Bracket, Hinge Bar, inside of the Lower 3-point Hitch Pins Bracket. If the Hinge Bar Bracket can NOT be slid to the necessary position to correct the Rake Width but, the windrow width is to the desired setting, it may be necessary to swing both halves of the Rake in or out by repositioning the Width Positioning Brackets to their No.2 hole positions for wider raking or to the No 4 hole positions for narrower raking. After the hole positions have been changed, the Tines pressure and Telescoping Rod and Spring assembly settings will have to be checked and readjusted, if"n-ecessary. MAINTENANCE Hardware Fig. 24 After the first hour of operation, check all attaching hardware, especially in the areas of the Tines and Bearings. Hardware torque should be checked on a routine basis after every 10 hours of operation. 18

19 Lubrication (Figs. 25 & 26) The WR308 and WR310 Finger Wheel V-Rakes MUST be routinely lubricated to promote long life and smooth operation. All points illustrated, as applicable, should be lubricated after every 10 hours of operation. On all units, a fitting is provided on each Main Frame Bearing for the Width Adjustment. WR308 Rakes (before Serial #2663) are provided with a total of (8) fittings on the Finger Wheel Bearings and a fitting on both Main Turning Bars. WR310 Rakes (before Serial #2403) are provided with a total of (10) fittings on the Finger Wheel Bearings and a fitting on both Main Turning Bars. For a WR308 Rake (after Serial #2662) and a W R31 0 Rake (after Serial #2402) NO other grease fittings are provided besides the fitting on each Width Adjustment. Besides grease fittings, apply oil to the Telescoping Rod and Spring on each Flotation Spring assembly, on all hinge points on the Finger Wheel Carriers, on the Width Adjustment Bracket hinges and, on the Pins and inner portions of the Adjustment Brackets. In addition to lubrication points on the Rake, BE SURE to routinely lubricate the hinge and 'adjustment points on your tractor's 3-point hitch.
